A battery assembly device with charging and discharging protection is provided. The aforementioned device includes a plurality of serially connected battery modules and each of the battery module further includes one or a plurality of battery units, a plurality of serially connected first diodes which are parallel connected with the battery unit, a protection circuit including a second diode and third diode which are parallel connected to each other, and a fourth diode. Aforementioned protection circuit is serially connected with the battery unit and configured between two connection points of the battery module, electrode polarity of the second diode and electrode polarity of third diode at connection point are different, and the fourth diode are configured between the two connection points of the battery module and its electrode polarity are different with the connection point of the battery unit. Aforementioned device enables the specific circuit loop formed by specific diodes to bypass the disabled battery unit so as to avoid the disabled battery unit effecting the operation of whole battery assembly device.
